Fulvestrant Usage And Synthesis
Indications and Usage Fulvestrant is a muscle injection drug developed by the company AstraZeneca and is suitable for treating postmenopausal women with estrogen receptor-positive metastasized breast cancer whose condition continued to worsen despite antiestrogen treatment. Fulvestrant is the only antiestrogen drug that can be widely clinically used following unsuccessful tamoxifen treatment. This drug is a type of endocrine therapy, so it will not cause any adverse effects commonly seen in chemotherapy, giving it relatively good patient compliance. Multiple clinical trials have found that 250mg Fulvestrant is effective and consistently safe as a second line of treatment for advanced breast cancer.
Mechanisms of Action Many breast cancer cells contain estrogen receptors (ER), so estrogen stimulates breast cancer growth. Fulvestrant is a steroid estrogen receptor antagonist, and its chemical structure is similar to estradiol, except that its 7α position contains a linking group. Fulvestrant is a 17β-estradiol alkylamine analogue, and it binds with, prevents, and decreases ER to inhibit the estrogen signal transduction pathway. It binds competitively with ER, has a similar affinity with ER as estrogen, and inhibits gene activation stimulated by estrogen, thus affecting necessary estrogen-related processes in cell circulation. Its fulvastans have a similar affinity with ER as estrogen and is 100 times that of tamoxifen.
Pharmacokinetics Fulvestrant has a relatively poor oral bioavailability, so it is commonly injected into the muscle with lipids as excipients. In an open, random and multicenter study on postmenopausal women with advanced breast cancer, one 5ml or 2 2.5ml dosages containing 250mg were injected, and their pharmacokinetics and poisonous side effects did not differ greatly, while its blood concentration was dose-dependent and had individual differences. In the 7-day treatment period, serum LH, FSH or SBHG levels did not change significantly. This drug does not pass through the blood-brain barrier and will not cause side effects such as vasomotor symptoms.
Adverse reactions Fulvestrant causes relatively fewer side effects, including brief vaginal bleeding, body odor change, and sleepwalking. There have not been any reports of effects such as vaginal dryness, weight gain, blood clotting abnormalities, thrombus formation and libido change, and characteristics such as facial flushing and sweating are not affected. A small-scale stage III clinical trial on 19 women with metastasized breast cancer who used this drug showed that its clinical efficacy was 67% and there were no serious safety issues. It showed that continuous monthly injections were crucial and that it was well-tolerated, with only slight swelling and paint at injection site, while facial flushing, uterine lining thickness, sex hormone binding globulin levels, follicle stimulating hormones levels, and luteinizing hormone levels all showed no change.
Chemical Properties White Powder
Uses A novel steroidal estrogen antagonist reported to lack any partial agonist activity. Antineoplastic (hormonal).
Uses antiestrogen
Definition ChEBI: A 3-hydroxy steroid that is 17beta-estradiol in which the 7alpha hydrogen has been replaced by a nonyl group in which one of the hydrogens of the terminal methyl has been replaced by a (4,4,5,5,5-pentafluoropentyl)sulfinyl group. An estrogen receptor antagonist, it is used in the treatment of breast cancer.
Biological Activity A high affinity estrogen receptor antagonist (IC 50 = 0.29 nM), devoid of any partial agonism both in vitro and in vivo . Also high affinity agonist at the membrane estrogen receptor GPR30.
